Investigate feature flagging services

[Harjot1Singh]

Investigation

Look into feature flagging services that we can use. This is crucial for building features. We are looking for something that has:

• An OSS friendly plan (free or heavily discounted)
• Feature flags
• Feature flag variables
• A/B testing (or experiments)
• Optionally, scheduled feature flags. Not really sure on how many services offer this, but this would be great
• Audiences

We also need to know how offline-friendly the FF service is:

• Does it pull down the state of the feature flags on app load? => better connectivity
• Does it cache the state between app loads? => offline support

Outcome

• Table/List of potential services with
  • Name
  • URL
  • Cost to us
  • Additional Features beyond the above list
  • Missing feature of the above list
  • Brief answers to offline-friendly questions above
• Recommendation for which service to use
• A new ticket to register for and implement the feature flagging provider/populate rest of epic

Outcome Going with Split! There is a way of doing timed releases: https://help.split.io/hc/en-us/articles/360053285391-How-to-do-a-timed-release-of-a-feature-toggle-Split-On-Treatment-.

We should test this works as expected.

If Split is not sufficient, we'll look at Unleash as the next priority.
